Tiamat, the Scaled Tyrant is the evil queen of dragons. She is a fearsome god of greed, envy, and hoarded wealth, and the patron of most chromatic dragons. She is the sworn enemy of Bahamut.[4]


Tiamat is depicted as a massive, five-headed dragon, with each head a different color of chromatic dragon, and her leathery wings spread poisonous clouds.[2]

Commandments of the Scaled Tyrant

Commandments of the Scaled Tyrant

  • Amass wealth, and spend little. The gold, and the power that comes with it, is sufficient reward.

  • Do not forgive or forget an indignity to yourself. Let no affront go unpunished.

  • Take what you covet. Those without the strength to defend their dominion are not worthy to have a dominion.


During the Age of Arcanum, Tiamat created one of the Arms of the Betrayers, given to her chosen champion of Ghor Dranas: the Will of the Talon, a war pick with the life force of a bone devil.[6] One of the Vestiges of Divergence is also associated with Tiamat: the Wreath of the Prism.[7]

Tiamat is imprisoned in Avernus, the first layer of the Nine Hells.[2]

Tiamat sent visions of a locked-away loop of golden thorns and gems to her follower Arkhan in his dreams. He sought out this artifact and, with the help of a group of mercenaries, eventually acquired the Wreath of the Prism from the Vault of Shumas in the Aggrad Mountains of Marquet.

Calianna Mordsson, a sorcerer of draconic origins who escaped the Cult of the Caustic Heart, sought the help of the Mighty Nein to find and destroy an artifact that would allow ritualistic communication with Tiamat before the cult could acquire it. The adventurers did find the bowl in the possession of several merrow, and Yasha was able to destroy the magic item with Magician's Judge.
